Timeline: How Iran-Pakistan Conflict Has Escalated In Past Decade

Pakistan on Thursday said it conducted air strikes against "terrorist hideouts" in Iran, days after Iran carried out missile and drone strikes in its border province of Balochistan against the Jaish al-Adl group.

"A number of terrorists" were killed during the intelligence-based operation codenamed "Marg Bar Sarmachar", Islamabad said, with media reports claiming that the Baloch Liberation Front (BLF) was the target of Pakistan's strikes.

Iranian media said several missiles hit a village in the Sistan-Baluchestan province that borders Pakistan, killing at least nine people.

Jaish al-Adl (JaA), a Sunni Salafi organisation that operates in southeastern Iran and the western Pakistani province of Balochistan, has been launching attacks against Iranian border guards since 2013. JaA, which is blacklisted by Iran as a terrorist group, was formed in 2012 and wants the independence of Sistan and Baluchistan province in Iran.

On the other hand, the Baloch Liberation Front seeks independence for Pakistan's western province of Balochistan. They are among the insurgents who have often launched attacks in parts of Pakistan.

Iran and Pakistan have had rocky ties in the past, but the latest air strikes are the highest-profile cross-border intrusion in recent years.
